Scuba Diving At Boulder city Thailand

Boulder City in the south of The Similan Islands of Thailand is a challenging yet exciting PADI scuba diving site. With crystal clear and nutrient-rich tropical waters, divers can see a wide range of marine life ranging from the small and shy Jawfish (endemic to the archipelago) to the majestic but harmless whale shark. Exactly which of the more than a dozen dive locations in the Similans offer the best scuba diving in Thailand is a matter of opinion, taste, and also depends on the water conditions on the day of diving.

Diving at Shark Fin Reef - Similan Islands

One of the larger dive sites at the Similan Islands in Thailand is a place called Shark Fin Reef. Its name derives from the granite boulders which break the surface at low tide and have the appearance of the dorsal fins of three huge sharks. It’s located on the east side of island 3 at the Similans, in the south of the chain. Depths, visibility, coral health and marine life are all excellent, even after the devastating tsunami in December 2004.

Due to its size, Shark Fin Reef can actually be dived twice in a morning or an afternoon. It’s about one kilometer long and lies from north-west to south-east.
